A:Answer The lock does not need wifi for use. This particular model not only comes with 2 physical keys for emergency use (or whenever you choose to use the keys) and a touchpad that lights up allowing for the input of the programmed passcode. Usage of the smart module and the sensor is purely optional, however access is not allowed from anywhere unless that module is installed. For security purposes, even with the wifi module installed and connected to the internet, for me to use the auto unlock feature or other smart features, my phone with the app must be on Bluetooth, the same wifi SSID, and must be in range of the lock.
